  GStreamer | gst-plugins-bad | Ver: HEAD CVS
           Summary: Seeking in pipeline with videoparse crashes
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED
          Severity: critical
          Priority: Normal
         Component: gst-plugins-bad
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: stian.selnes at gmail.com
         QAContact: gstreamer-bugs at lists.sourceforge.net
     GNOME version: 2.21/2.22
   GNOME milestone: Unspecified


Steps to reproduce:
1. Short python script producing the bug may be found at
http://www.pvv.org/~stianse/files/gst-bug/
2. Run script. This launches the pipeline "filesrc location=./bus_cif.yuv !
videoparse width=352 height=288 ! ffmpegcolorspace ! ximagesink".
3. Start video with "play" button and hit "next" button soon after. This will
run a seek command similar to "self.pipeline.seek_simple(gst.FORMAT_DEFAULT,
gst.SEEK_FLAG_FLUSH, 30)".
